The film screenwriter Graham Moore is an avid fan of Alan Turing. The influence of this mathematician was everywhere in the American space camps and computer programming summer camps he participated in as a teenager. After realizing Turing's great inspiration to him, Moore has been looking for opportunities to bring Turing on the screen. When the copyright of "Alan Turing Biography" was taken down by the producers Nora Grossman and Ido Ostrowsky, Moore immediately signed a script contract and paid nothing. When creating, "restoring a real Turing" became the driving force for his creation. But accuracy is not easy. A large number of Turing's work records were destroyed in World War II, and the remaining fragments became highly classified. Moore had to look for details from the outside and the impact of these organizations on him. The result is quite surprising. The most powerful information that can be found about Turing's work with MI6 after cracking the code comes from the diary of "007" author Ian Fleming.
The main events in the movie are all real, but they have to be exaggerated. In the film, Turing named the machine he developed "Christopher". In reality, the name of the machine is Bombe, and the screenwriter made up this segment. Because the original author Andrew Hodges and many historians believe that Turing's love for computers and artificial intelligence is inseparable from the feelings between him and Morcom. Adding this episode is an artistic exaggeration to fully express Turing's long and true obsession. The role prototype of Hugh Alexander in the film is half Hugh Alexander and half Gordon Welchman, another mathematician in the team. The police officer Nock who interrogates Turing in the movie is not a real person either. He symbolized the institutionalized homophobia of that era to show that the people who arrested and persecuted Turing were not cruel lunatics but the most ordinary people. At the same time, in order to protect the police officer who had interrogated Turing in reality, Moore gave the character a pseudonym.
